Hey guys,
Anyone know a source for a PCI express connector with the little board lock tab on the end? I searched digikey and didn't see any. I guess it doesn't have to be molded in one piece if there is some sort of separate board lock piece that clips on or something. Any help would be great. It does have to come from real distributor through. No Aliexpress or ebay specials.
This thing....

Almost certainly will be a Foxconn or AMP part. Though I don't have any more info than that.
Edit: Annnnd, I'm right

I didn't find it on digikey either but, wow, have you seen this cable? PCIE x16. That is a sexy cable.

Cool. Thanks. But... MOQ of 1440, while not that high in the grand scheme of things is more than I can commit to now. I'm a little suprised there aren't more sources considering just about every motherboard I can find has one in it, and has for the last 10? years.

Yeah, outside of AliExpress or Ebay, you may be stuck with that. You might just be well off sucking one out of another motherboard.

Unfortunately I need a reliable source in the 100s. I'll keep looking.
As a side note, I think I'm a pretty good reworker but I've had TERRIBLE luck desoldering anything through hole from a PC motherboard. Too many plane layers.

The magic words for the search are:
PCI Connectors x16 GRAPHICS CARD RETENTION MECHANISM
(Sorry for the caps, it was a cut and paste job)
For example at mouser:
http://www.mouser.com/Search/Refine.aspx?Keyword=10042618-002LF (http://www.mouser.com/Search/Refine.aspx?Keyword=10042618-002LF)
Edit: Almost 15,000 in stock and minimum purchase 1, but I would buy some samples before committing just to make sure they work for you.
Found the drawing specs for the latch:

And I guess they will work well with fci's connector offerings:

Seems like other vendors has the latches as well:

https://octopart.com/search?q=10042618&start=0 (https://octopart.com/search?q=10042618&start=0)
Edit:
Also by searching Octopart for the fci series it finds the following:

Find chips same results:

I think the ones with TLF at the end have the locking mechanism, but it seems you'll have to contact digikey since there is no stock. But plenty of stock for the separate latch.

You... miguelvp... are my new personal hero!

Don't thank me just yet, dealing with two parts instead of one might turn out ok, but then again you might be cursing me later on if it's hard to mechanically match both parts in the assembly process, that's you probably should try a small sample before getting hundreds of them.
Unless you can get digikey to get you some of the one part only with the 8 week lead time.

Two pieces actually looks like a really clean flexible solution for what I'm looking to do. Definitely not jumping into volume without prototyping first.
